Based on an idea by Eric Sellers, a master sergeant in the U.S. Air Force Reserves whom Marz first met several years ago, The Historians follows a special Air Force squadron who must pursue a rogue member through time. It’s planned for March 2013 release. In a blog post, Marz implied “creative differences” with Sellers led to the abrupt departure.

“This was not my choice, nor the choice of artist Jamal Igle, or publisher IDW,” he wrote. “I’m disappointed the project did not work out as planned. To my knowledge, Jamal has left the project as well. It’s best to describe the situation as one of creative differences, and leave it at that. I hope to work with both Jamal and IDW at some point in the future. I wish the best of luck to The Historians moving forward.”

In a statement to Comic Book Resources, Marz added, “Sometimes projects don’t work out as expected. That’s the case with The Historians, unfortunately. I’m not one to tell stories out of school, but ultimately the team of me and Jamal Igle weren’t the right fit for the project. I do want everyone to know that there are no problems between me, Jamal Igle and IDW. I’m looking forward to working with both Jamal and IDW in the future, hopefully the near future.”

Igle similarly wrote, “I still have a great relationship with Ron and the staff at IDW, and look forward to a healthy future with all parties involved.” On a happier note for the artist’s fans, Igle said the opening in his schedule means he can begin working on the first Molly Danger book next month rather than waiting until spring, shifting release from October 2013 to July 2013.
